Abstract

This document defines the mesh link establishment (MLE) protocol for
establishing and configuring secure radio links in IEEE 802.15.4
radio mesh networks. MLE extends IEEE 802.15.4 for use in multihop
mesh networks by adding three capabilities: 1) dynamically
configuring and securing radio links, 2) enabling network-wide
changes to radio parameters, and 3) detecting neighboring devices.
MLE operates below the routing layer, insulating it from the details
of configuring, securing, and maintaining individual radio links
within a larger mesh network.
